The left wing 300LW of the rear plate 300 can block the view of the display panel 100 more, as the margin distance DM is greater. The viewing angle of the display panel 100 may get smaller, as the margin distance DM is greater.

The wings of the rear plate 300 may be integrally formed with the flat plate portion 300FP of the rear plate 300. For example, the rear plate 300 can be formed through the process that melted material is poured into a cast and hardened. For another example, the rear plate 300 can be formed through the process that the rear plate 300 in a flat state is pressed and bent.

The wing of the rear plate 300 may refer to a bent portion of the rear plate 300. The wings of the rear plate 300 may be positioned in the same plane when the flat plate portion 300FP has not been bent yet.

The direction in which the upper wing 300UW is bent may be different from the direction in which the right wing 300RW is bent. The upper wing 300UW and the right wing 300RW can meet at the first corner C1. The bent direction of the rear plate 300 at the first corner C1 can be directed to the left wing 300LW and the lower wing 300DW. In this case, there may be a concern that a phenomenon (hereinafter referred to as a “wrinkle phenomenon”) that the rear plate 300 at the first corner C1 may wrinkle.

The wrinkle phenomenon at the first corner C1 can be suppressed if the degree of bending of the upper wing 300UW becomes smaller the closer to the first corner C1 from the center of the upper wing 300UW. The wrinkle phenomenon at the first corner C1 can be suppressed if the degree of bending of the right wing 300RW becomes smaller the closer to the first corner C1 from the center of the right wing 300RW.

The wrinkle phenomenon at the second corner C2 can be suppressed if the degree of bending of the upper wing 300UW becomes smaller the closer to the second corner C2 from the center of the upper wing 300UW.
